Chapter five - Dan The Next Big Thing Guide

Break free before Zelssius returns with a chip

When Zelssius goes away, talk to professor Flay who is trapped in a cage hanging over Dan. Talk with him about corrosive properties of his saliva. Ask him to spit on handcuffs blocking Dan. Although because of the distance professor won't be able to exactly point at Dan's left hand, but he will release his left foot. Use it to activate a nearby lever - you'll lower the cage with Flay.

Accost professor again. Unfortunately he is no longer angry so he can't spit anymore. You can try to get him angry but with no success. In this situation call Zelssius who is in the backroom (use a speech bubble cursor on a passage below a professor's cage) and tell him about Flay's wicked intentions against him. When Zelssius will spray professor with insecticide, he'll get mad and now spit a correct place. After a while they are both free.
